Application January 28,

2 Claims.

This invention relates to improvements in shingles, and one or" the objects of the invention is to provide roofing shingles of sheet asphalt or other materials, which may be out out of a rectangular blank without waste.

Another object is to provide composition or other shingles which will have the appearance of, and lay, when applied, like American or Dutch lap method shingles, all vertical and horizontal edges being at perfect right angles.

Another object is to provide shingles of this character with improved interlocking means to eliminate the interlocked slots heretofore employed, as such slots have a tendency to cause the material to tear, especially in cold weather.

With the foregoing objects outlined and with other objects in view which will apear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing,

Fig. 1 is a plan view showing the lines of severing of a sheet of asphalt or the like to convert the same into a number of roofing shingles without waste.

Fig. 2 is a plan view of one of the shingles.

Fig. 3 is a plan view of a portion of a roof covering formed by my improved shingles.

In the drawing A designates a rectangular sheet of asphalt roofing material or the like, which, in the manufacture of the shingles, is cut transversely on the lines B to provide a number of shingles C. It will be observed that such cutting provides one edge portion of the shingle with an upper rectangular tab 5, and a lower tab 5*, the latter having its upper edge of irregular shape to provide a main notch 5 and an auxiliary notch 5.

At the opposite edge portion, the upper corner of the sheet has an angular recess 6 and at the lower corner, there is a similar recess 6 the upper edge 6 of which is irregular to correspond with the upper edge of the tab 5 In laying shingles of this type, the tab 5 hooks into the lower edge of the long tab 6 with the side edge portion 3 of each shingle overlapping the side edge portion 4 at the opposite side of an adjacent shingle. The tab 5 goes under the portion 6 at the upper end of the shingle, and a nail 8 through the portion 6 holds both securely. The tab 5 also acts as a guide to keep the shingles perfectly straight or in horizontal alignment, and a nail 7 is passed through the part 4 of each shingle to securely fasten the same to the roof.

From the foregoing it will be readily seen that when shingles of this type are nailed in place, their upper and lower edges will be at right angles to the vertical edges of the shingles, or in other words, conform to the American or Dutch lap methods.

1931, Serial No. 511,862

Owing to the notch construction at 5 and 6 clearance is provided for the parts to be hooked into one another without liability of tearing. Recess 5 is the same height from the bottom edge as recess 6 for the purpose of keeping the bottom edges in alignment.

It is obvious that the shingles need not be laid exactly as shown, for they can be placed upside down, and will still have the appearance on the roof of rectangular shingles.

It is believed from the above that the construction, use and advantages of the improved shingles may be readily understood, and I am aware that changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.

What I claim and desire to secure by Letters Patent is:--

1. A substantially rectangular shingle having at the opposite lower corners thereof, a projecting tab with a serrated upper edge, and a recess complementary to said projecting tab, respectively, said serrated edge being composed of two V-shaped notches, the bottom of the notch adjacent the jointure of said projecting tab to the shingle body being at the same distance above the lower edge of the shingle as is the length of the outside vertical edge of said projecting tab, the bottom of the other notch being below the first named notch and between said notch and edge, whereby said shingle may be interlocked with an adjacent shingle of similar construction.

2. A substantially rectangular shingle having at the opposite lower corners thereof, a projecting tab with a serrated upper edge, and a recess complementary to said projecting tab, respectively, said serrated edge being composed of two V- shaped notches, the bottom of the notch adjacent the jointure of said projecting tab to the shingle body being at the same distance above the lower edge of the shingle as is the length of the outside vertical edge of said projecting tab, the bottom of the other notch being below the first named notch and between said notch and edge, whereby said shingle may be interlocked with an adjacent shingle of similar construction, said shingle being provided at one corner of its upper end with a rectangular laterally projecting tab, and at its other corner with a recess conforming in size and shape to said tab.
